(54) Heat transfer member and method for manufacturing same


(57) A heat transfer (100) member for a heat exchanger, is press-formed of a metallic thin sheet material into a prescribed shape by means of molds of a press forming device so that the heat transfer member has on at least one portion thereof a heat transfer face having opposite surfaces, which are to be brought into contact with heat exchange fluids, respectively. The heat transfer face comprises at least one set of irregularity patterns arranged in a row. Each of the at least one set of irregularity pattern units comprises (i) a central pattern portion (111) having a plurality of recesses or projections provided with a prescribed pitch, (ii) a pair of heat exchanging irregularity pattern portions (112) provided on opposite sides of the central pattern portion (111) so as to be symmetrical with respect to the central pattern portion and (iii) at least one boundary pattern portion (113) provided on at least one of respective outer sides of the pair of heat exchanging irregularity pattern portions (112) so as to be adjacent to the respective outer sides thereof. The boundary pattern portion (113) has a prescribed width and a plurality of recesses or projections provided with a same pitch as the plurality of recesses or projections of the central pattern portion (111) so as to be in parallel therewith.
